[0022] See also Figures 1 to 5 The present embodiment provides a shock-absorbing and drop-proof mobile phone protective case, which also includes a transparent TPU frame 1, a TPE anti-collision strip 2, a PC back panel 3 and a camera ring 4.

[0023] The transparent TPU frame 1 has a long groove 11 extending along its inner edge in the middle of its inner wall, and the TPE anti-collision strip 2 is disposed within the long groove 11. Preferably, a long concave cavity 21 is provided on the inner wall of the TPE anti-collision strip 2 at a position corresponding to the corner of the transparent TPU frame 1. The long concave cavity 21 provides additional elastic space for the TPE anti-collision strip 2, enhancing the shock absorption effect, helping to disperse the impact force and reduce damage to the mobile phone. Several round pits 22 are evenly distributed on the inner wall of the TPE anti-collision strip 2, which can increase the shock absorption effect and improve the drop resistance of the mobile phone. Preferably, several concave strips 12 extending along its long side are arranged in parallel within the long groove 11, and convex strips 23 that match the concave strips 12 are provided on the outer wall of the TPE anti-collision strip 2. The combination of the concave strips 12 and the convex strips 23 can improve the bonding tightness between the TPE anti-collision strip 2 and the transparent TPU frame 1, ensuring that the TPE anti-collision strip 2 will not shift when impacted, thereby providing better protection. Preferably, the corners of the transparent TPU frame 1 are thickened. The thickened corners can enhance the structural strength of the transparent TPU frame 1, so that it can better protect the mobile phone from damage when it is impacted by external forces.
